[RE-wrenches] Ilsco SGB bonding lug

[Jason Szumlanski]

The WEEB-LUG is great for rail bonding:
http://www.we-llc.com/grounding-lug.html

It is UL467, marked Outdoor Use, made of tin-plated copper. The only
disadvantage is that the stainless steel clip must be sacrificed if the lug
is moved - a disadvantage of all WEEB grounding products.
